Abstract: The analysis, carried out in the framework of the diffractive approach, of a number of experiments on interaction of the neutron-rich exotic nuclei 6He and 11Li with nuclei allows one to make the conclusion about the presence of a dineutron configuration (dineutron) in 6He and the absence of that in 11Li .
